Query: Presto - Deprecating TD_SESSIONIZE for TD_SESSIONIZE_WINDOW

The TD_SESSIONIZE function in Presto, used to sessionize web log or other event log data, has been deprecated in favor of its replacement function, TD_SESSIONIZE_WINDOW. TD_SESSIONIZE_WINDOW, added to Treasure Data in 2016, is a true Presto window function, that offers better performance, lower memory usage, and consistently correct results. TD_SESSIONIZE can in some circumstances use excessive memory or return inconsistent results on the same input.
